To (ZZZ whom e't may concevm:

Be it known that l, HANS Burs, a citizen of-the Swiss Republic, and resident of Basel, gwitzerland, have invented new and useful Quaternary Bases of the Camphor Series and Processes of Making Same.

I have found, that quaternary bases of the camphor series are obtained by prepare ing theproduct of addition of e iertiery 21min to camphylbrommethene in presence of a convenient solvent, according to fihe 0n the contrary, when cemphylchlormethane is employed for instance with triinethylemin, i'zhe' reaction ooouis-aei'sordiug to the formule:

that is "to say there is formed methylenecemphor and triinethylammonium chloricl.

This reaction occurs also as secondary react-ion, when eamphylbi oinmeShane is eniployecl, but the methylenecemphor formed can always be transformed into hromid end $l1ereiore-he made again utilizahle for the above reaction Ewampi'e.

of camphylhromby the splittingofif of H131 1S recuperei eel and can immediately be restrahsformecl imo eemphylhrommethane by its treeaiiiehi Wiibh hydrohromio acid.

he mixture of trimeth'ylemin hydrobro mid Wii'h the quaternary ammonium base is treated Wiih hot; chloroform, wherein the 5 said base is reeoily soluble, while the former is enfiireiy insoluble therein. iion, the iJrimethylcemphormeihylammohiumbroinicl is precipitated from the filtrate by an addition of a little quantity of ether. It constituies colorless, fine leaflets, easily soluble in elehol, in Water and hot chloroform and containing, at ordineryiemperafiure, stili inwo molecules of trimethyl om moniumhroinici combined. When heated they melt at first at 192 C. While the above specified 2 molecules of niumhromicl are separated, become again solid oi higher temperature and melt then with decomposition at 25e #1).

What claim is:

\ 1. As new produces, ihe herein lrihed irialkyloamphormethylemmonium heloiols, which constitute colorless crystals, easily soluble in alcohol and in weier,

As e new erisiele herein described trime'bhyleemphormefihylunimoniumhromicl, which constitutes colorless,

leafless and hoe chloroform and containing at ordiiiery temperaiure jwo molecules of combined trime'thylaminoniumbromid, thesziid leaflets melting ei; 192 while the said two molecules of 'arimeihyiainmoniumbromid are separated, become then again solid and melh finally iii; 250 with iflecomposition.

3. The herein described process for the manufacture of quaternary bases of ihe ram phor series, eohsis'ning in adding e tertiary omiii eomphylbi'ommethzme in presence of a. convenient solvent In witness whereof I have hereunzo signed my name this day of February, 1921, in the presence of two subscribing Witnesses.
